Astilboides tabularis. It is the perfect plant for a shady area and does best in heavy, wet soil. It's also a good choice as a marginal plant next to a large pond. Astilboides does flower, sending up creamy white, Astilbe-like plumes in July, but the leaves are the plant's main attraction. It can take several years for a good-sized clump to form, but allow plenty of room for growth when planting, as a single plant can grow to 120cm (4ft) wide.
Honeysuckle 'Goldflame' is a strong climbing plant with delightfully fragrant flowers. It grows with incredible speed and will thrive anywhere. Noted for its exquisite fragrance which is stronger in the early evening in order to attract night moths.
Candytuft (Iberis Sempervirens) is incredibly floriferous. Rewarding spring flowering plant with a creeping habit. It flowers in great abundance covering the ground with a carpet of white flower clusters. Stays green during winter.
