Plants You Can Walk On

The tulips and daffodils have been blooming beneath golden forsythia, and crocus and hyacinth surrounding the magnolias. Hellebores have been pushing their way upwards displaying their proud colourful heads as they unfurled and all of our favourite perennials are gradually emerging from the soil seeking the warmth of the sun.

If you have recently moved into the new home of your dreams, by now you have the furnishings in place and d├ęcor to your liking. Now, I urge you to focus on the continuation of your home into the “outside rooms”. With thoughts of summer ahead, and plans for neighbourly get-togethers around the pool, patio or garden many ideas will start to evolve in your own head; it’s difficult to know where to start.

Allow me to help get you on track and keep you there.

If you are considering a lawn area in your landscape, consider this alternative - wonderful little plants called ‘Stepables’. These are tough, easy to grow perennial plants that endure light to medium foot traffic. This means they take various degrees of walking on. Have you ever strolled through a friend’s garden where they had planted creeping thyme between the crazy paving stone pathway? A wonderful aromatic fragrance is released as soon as your foot brushes against the thyme.

Stepables are just the job for filling nooks and crannies around pathways, pools and borders and most of them bloom profusely in full sun or part shade. Once established, most plants can be mowed or cut with a weed-eater or edger. Here are just three from the large selection available, all of which have been selected for moderate foot traffic. This allows for foot traffic passing once or twice a day.

Chamaemelum nobile (Roman Chamomile)
This plant with dense bright green foliage, releasing a delightful aromatic fragrance when disturbed, grows to a height of 4-12in. (10-30cm), forming a tight mat. Small yellow or white flowers that rise above the plant in summer are usually removed to keep it short and manageable. This plant requires a shady to partly shady location and is hardy to Zones 5-9 (up to Barrie).

Euonymus fortunei ‘Kewensis’
This slow-growing plant, attaining a height of just 2in. (5cm) makes an excellent evergreen ground cover and is frequently used for controlling soil erosion on banks; coping with considerable wear and tear. The small green leaves turn a most attractive burgundy colour in winter. Grow in sun/part shade in Zones 5-9.

Lysimachia nummularia (Creeping Jenny)
Although this plant prefers moist areas it will also accept drier conditions covering the ground with bright yellow flowers dotted amongst the creeping small green leaves. Blooming in part sun to shady conditions, Jenny will grow to a height of 2in. (5cm) as she spreads her attractive yellow carpet readily accepting medium foot traffic. Hardy in Zones 4-10. An added bonus - Jenny also looks great trailing over walls or planted in hanging baskets!

At this time of the year there are so many exciting perennials to introduce to you I could continue talking until fall. However, I must introduce you to some of the plants from my Garden Perennial Collection, which includes over fifty varieties, all grown for their outstanding features and proven garden performance, as well as being favourites of mine. These I have divided into six garden categories and over the course of the next few weeks we will quickly peek inside each one and select some exciting specimens to review.

This week I have selected the Shadow Garden where plants have been selected to thrive under filtered leaf canopies, lighting up dark corners of shadow.

Athyrium nipponicum ‘Pictum’ (Japanese Painted Fern)
This is a very attractive, lacy-leafed fern, that forms a dense mound of olive green arching fronds, displaying a metallic sheen of grey and red. Growing to a height of 12-24in. (30-60cm), this is an extremely easy fern to grow and certainly adds a bright touch to the shade garden. The Painted Fern enjoys moist, humus soil and is hardy in Zones 4-9.

Lamium maculatum ‘Pink Pewter’ (False Salvia)
Clusters of clear pink flowers appear sporadically from spring until fall on this engaging silver and green-leafed groundcover. The metallic leaves continue to attract, even when the weather turns cold, as they turn bronze in colour. Select this vigorous plant for season-long performance. A hardy plant, good to Zone 2 and perfect for lighting up the shadows.

Hosta ‘Grand Tiara’ (Plaintain Lily)
Even if you already have more hostas than you can name you will not forget this one. ‘Grand Tiara’ is the most striking of the Tiara series, displaying a broad gold leaf with a small green centre. H. ‘Grand Tiara’ is particularly attractive early in the season and can be planted in light or full shade and still be the centre of attention. Hardy to Zone 2 (Edmonton).
