 Introducing Heirlooms for the Beginner Gardener Introducing Heirlooms for the Beginner Gardener
By wildflowers on July 29, 2011

Heirlooms are a perfect choice for the beginner gardener. The seeds of many of these old cultivars have been saved and passed down for generations because of their easy-to-grow habits. They are those wonderful old fashioned flowers that your grandmother grew forever in her garden, or those delicious tasting tomatoes that you might remember eating as a child. But it doesn't stop there; as you begin to consider growing heirlooms, you will discover many unique and interesting flowers, herbs, vegetables and fruits.

"Some stocks are grown as annuals (the "Ten-week Stocks"). These varieties are sown in spring (generally from March onwards in colder areas, earlier in regions with mild winters). They give a good summer flower display. Other varieties take longer to develop and are treated as biennials. These are often referred to as "Brompton stocks". In cool temperate regions they are generally sown in summer (June and July) to flower in the following spring. The extra trouble of overwintering the plants is compensated for by the showy spring floral display. In hard winters there may be some mortality and a well-drained sheltered site suits them best.

Double-flowered stocks are prized by gardeners for their floral display but are sterile. They therefore have to be produced from the seed of single-flowered plants. The double-flowered form is caused by a recessive gene variant (allele) in the homozygous condition. Therefore, according to the Mendelian laws of genetics, heterozygous single-flowered stocks should produce ["throw"] one quarter doubles in their offspring and one third of the singles should be pure breeding singles incapable of throwing doubles."
