Bulbs, Forget-me-nots, Primroses and Wallflowers are the low-growing heralds of spring. Millions of Wallflowers are planted every year during October and theon the erect spikes open in March or April (Wallflower) or May (Siberian Wallflower). Pinch out the tips of young plants before transplanting them in their final quarters. Grow them close to the house to enjoy the fragrance.
