Joe's Perennial Highlights

This Week’s Perennial House Highlights

Spring has arrived at Greenland, and our Perennial House is quickly filling up with beautiful classics, as well as unique collectors’ items, that will get your season started in a big way. Here are a few of the highlights available this week:

Pheasant’s Eye (Adonis amurensis)

A rare and stunning rock garden plant, this is one of the earliest blooming perennials, with large, bright-yellow, daisy-like flowers and attractive ferny foliage. Plants tend to go dormant and disappear by midsummer, so plant with companions that will take over the spotlight. Full sun, well-drained soil. Ht: 8-12 inches Sp: 12 inches Zone: 3


Japanese Cobra Lily (Arisaema sikokianum)

This rare and unusual conversation piece makes a unique addition to a shady garden or woodland. A relative of Jack-in-the-pulpit, this has showy purple, white, and green hooded flowers, and silver-marked foliage. Prefers rich, moist, well-drained soil in part shade. Ht: 12 inches Sp: 12 inches Zone: 4


Raymond Evison Clematis

Developed in the UK, these are considered amongst the finest Clematis in the world. Large and showy flowers appear twice per year, in late spring to early summer and again in late summer. Several varieties are available, with differing bloom styles and colors. We recommend planting against a heated foundation (preferably south-facing), 6 inches deep for best results. Prune annually in spring, above a set of buds. Require full sun and cool, moist, well-drained soil. Ht: 6-8 feet Sp: 3-4 feet Zone: 4


Martagon Lilies

This year we are carrying an excellent selection of martagon lily hybrids, and the first batch is available now – get them while you can at our great prices, as quantities are limited! These extremely hardy plants are great in full sun to part shade and form clumps of tall, sturdy stems with umbrella-like foliage. Many downfacing blooms with reflexed petals appear in June, and often have a spicy fragrance. A wide variety of colors are available. Note that these plants take a couple years to settle in before they really start growing, but our plants are large and robust, and are showing flower buds now! Ht: 4-5 feet Sp: 18-24 inches Zone: 2

Prickly Pear Cactus (Opuntia polyacantha)

Did you know there are several species of cacti native to southern Alberta? This is one of them! Prickly pear cacti are superior choices for hot and dry areas, and thrive in poor, sandy soil. The spiny pads spread to form a nice patch over time, and are resistant to pests. Showy flowers, typically yellow but sometimes in shades of peach, pink, orange, white, and red, appear in summer and are followed by sweet, edible fruit. Quantities are limited! Ht: 6-10 inches Sp: 24-30 inches Zone: 3


Double Fernleaf Peony (Paeonia tenuifolia ‘Rubra Plena’)

We have an excellent crop of this always-popular perennial this year. This unique peony  produces double, ruby-red flowers in late spring to early summer, before other peonies bloom. It also features unusual, very fine, fern-like foliage. Particularly in hot, dry years, these often go dormant and disappear shortly after blooming. But don’t fret, they will return the following spring! They are slow-growing and don’t like being moved, so pick a spot where they will remain undisturbed for several years. Moist, fertile, well-drained soil in full sun to light shade. Ht: 24 inches Sp: 18-24 inches Zone: 2

Hardy Grapes (Vitis spp.)

Our first shipment of hardy grapes has arrived! Excellent for fresh eating, jams and jellies, and wine making, our selections are well-suited to our climate and perform well given the right location. We recommend a warm, sunny area such as the south side of a house for best results. Ht: 15-20 feet Sp: 8-10 feet Zone: 3-4  Available right now are Marquette, Valiant, Frontenac and Frontenac Gris.
