4. R. ‘Dora Amateis’  (carolinianum x ciliatum) A very floriferous white (with a touch of pink) hybrid. Every spring it covers itself in flowers, hiding its dense, dark green foliage. Mounded habit. 30″h x 48″w. Highly recommended. Hopefully it will come this year. Zone 6. A few only.  (2 gal. – $30.00)


5. R. litangense – A very dwarf species now lumped in with the more common R. impeditum. Very similar to R. impeditum in its tiny grey-green foliage and purple-blue flowers but it is very slow growing. Bronzy winter foliage. To 1’h x 1’w. in many years. Ideally suited to the sunny rock garden. Zone 5. A few only.  (1 gal.)

13. R. ‘Baden Baden’ – (‘Essex Scarlet’ x forrestii v. repens) One of many named varieties of this cross. Deep cherry red bell-shaped flowers with a waxy texture on a low growing plant to 2′ high. Upright spreading in habit. Shiny dark green foliage. Zone 6a but appreciates some winter protection.  (1 gal.)


14. R. bureavii ‘Lem’s Form’ – A species with spectacular foliage. New leaves and stems are covered in rusty red hairs. Mature leaves are shiny green with thick rusty red indumentum. This  selection has narrower leaves than the type species. Flowers are creamy white with crimson markings. Compact and shapely in sun, tree-like in shade. Mid-season. Zone 5. Hopefully we will receive the right one this year. (1 gal.)


15. R. ‘Casanova’ – (‘Newburyport Belle’ x ‘Good Hope’) A Leach hybrid with yellow, pink and orange flowers giving an amber-pink effect. Lustrous green foliage. Well-branched, spreading, mounding habit. To 4’h. Zone 5. We had more orders than plants last year.  (1 gal.)


16. R. ‘Golden Gala’ – (‘Great Lakes’ x ‘Good Hope’) A proven performer in the Maritimes. Pink buds open to delicate pale creamy yellow flowers fading to ivory. Floriferous. Dense, glossy dark green foliage on a well branched, compact rounded plant. Wider than tall. To 4′ high. A Leach hybrid bred in Ohio. Zone 5. (1/2 gal. – $10.00 or 1 gal. – $15.00)

20. R. piercei – Early, tubular bell-shaped scarlet flowers grace this species. Well branched, rounded habit with dense foliage. Thick brown indumentum. Definitely tender in Zone 6 but of interest for hybridizing. Worth a try in the Yarmouth area. A couple only.  (1 gal.)


21. R. recurvoides – Another species with  exceptional foliage. Long, pointed leaves with heavy white indumentum aging to orangy-brown. Flowers are  white or white tinged pink.

25. R. yakushimanum ‘Ken Janeck’ – Somewhat larger and deeper pink than ‘Mist Maiden’ listed below. (1 gal.)


26. R. yakushimanum ‘Mist Maiden’ – If you were to grow only one rhododendron, this should be the one. Its long narrow leaves have a tan-white indumentum. New growth is covered in silver tomentum. The dense foliage covers a plant which is perfectly symmetrical and broadly mounded in shape. An added bonus is the rosy-pink buds which open to form large apple blossom pink trusses which fade to white. Slow growing to 4’h x 11’w in 30 years. Best in a half day of sun. Zone 5.  (1 gal.)





These super-hardy hybrids, bred in Finland, are well worth a try almost anywhere in the Maritimes. Members who belong to RSC District 12 will have read about these plants in the Fall 1996 Journal of the American Rhododendron Society.

A few only of the B&B size.  (3 gal. – $60.00 or 90cm B&B – $75.00)


Cornus x rutgerensis – (florida x kousa) This could very well be one of the first introductions of these exciting hybrid dogwoods to Eastern Canada.

57. Daphne x burkwoodii ‘Brigg’s Moonlight’ – For those that know and love the cultivar ‘Carol Mackie,’ prepare to be blown away by this exciting new sport – a reverse variegation. Almost evergreen leaves are golden-yellow with a narrow mid-green border. Its parent grows to 3′ high x 5′ wide – this one is apt to be smaller. Pale pink fragrant flowers open in May.  Due to its high degree of variegation some shade may be required. A real show-stopper. Very slow growing thus the high price (our cost). We have been promised this but we aren’t holding our breath. Be sure to order it on the slim chance that we do receive it. Zone 5 or colder.  (1 gal. – $30.00)

60. Pieris ‘Brouwer’s Beauty’ – (floribunda  x japonica) This light green, evergreen ericaceous shrub is much hardier than the more common Pieris japonica and  intermediate between its parents in appearance. Flowers are more upright resembling P. floribunda. Airy red panicles of buds are held over the winter. Large panicles of small, lily-of-the-valley type flowers in spring. New foliage is glossy yellowish-green. To 6’h x 6’w. Zone5b. (1 gal.)


61. Pieris ‘Spring Snow’ – (floribunda  x japonica) Another hybrid variety similar to ‘Brouwer’s Beauty.’ Zone 5b. (1 gal.)

63. Viburnum x bodnantense ‘Dawn’ – Dense rounded trusses of small rose pink, sweetly scented blossoms are born very early – in March when little else is in bloom! A vigourous deciduous shrub with an upright habit.  Leaves are dark green turning reddish-purple in the fall. Flowers are frost resistant and are easily forced in winter. Zone 6. Not received last year. (4″ pots – $4.00 or 2 gal. – $15.00)





64. Corydalis flexuosa ‘China Blue’ – A selection of the species with cobalt blue flowers. Summer dormant in warmer climates this species will be in bloom for most of our growing season.

65. Hakonechloa macra ‘Aureola’ – A very slow growing weeping grass with rich golden variegated foliage. It looks like a miniature bamboo. Not invasive. For part shade as it scorches in full sun if dry. Very elegant, very choice. Perhaps the nicest of the small grasses. Looks great arching over a pot or  a wall. Zone 6. Not received last year.  (1 gal.)


66. Hellebores  x hybridus ‘Royal Heritage’ – (Lenten Rose) An aristocratic plant, this variety has rich reddish-purple flowers. Blooms very early in spring. Plant in light shade and prepare the soil extra deep incorporating plenty of compost and well rotted manure. Remove previous years foliage before flowering if tattered. Resents transplanting. Zone 6 or colder? A few only.

(3 gal. – $40.00)


66. Heuchera sanguinea ‘Splish Splash’ – (Coral Bells) Unlike most of the new varieties, this one has small leaves, a flatter habit and showy flowers. Leaves are heavily splashed with white giving a creamy effect. New leaves have a pink flush. Vibrant  red flowers in late spring on spikes to 20″ high. Foliage 5″ high. Evergreen. Light shade required as it scorches in the mid-day sun. Zone 4/5. (1 gal.)


67. Tiarella ‘Inkblot’ – (Foam Flower) Semi-evergreen with panicles of small, fluffy flowers in spring. This cultivar is a clumper with large shiny leaves which develop a large dark blotch. Flowers are white with a pink tinge. For shade to part shade. Zone 5. (1 gal.)
