Extra early, extra large blooms are the feature of this award winning sweet pea, “Mammoth Mix” is an excellent choice for early spring colour and the best strain for producing early cut flowers. The plants are early to flower, heat tolerant and produce well into summer.
The vigorous plants have long, strong stems which bear plenty of large fragrant blossoms. The Mammoth Mix contains a selection of stunning shades of crimson, lavender, salmon, deep rose, navy blue, rose pink, and salmon pink, these climbers will be perfect for that first sweet pea bouquet.
The "Mammoth Series" belongs to a type of sweet pea called an 'Early Multiflora Gigantea'. These varieties of sweet pea were developed before the Spencer’s variety and are popular with commercial cut flower growers, as they produce very large and good-quality flowers borne on long stems. The most popular series is the Mammoth Series, which is marked by the longest stems, and a very large flower. This series is also known for great uniformity in the flowering time across different floral colours.
If you have never seen this kind of sweet pea on long stems before, and don’t quite understand what all the fuss is all about…they are marvellous … guaranteed to make you fall completely in love with them.
Lathyrus odoratus 'Mammoth Mix' is a Fleuroselect Award Winner.
Early sowing is one of the secrets of sweet peas. In Zone 7 or colder, plant them in very late winter or early spring as soon as the soil is dry enough to work. (Do not wait to sow until last frost.)
In the coldest parts of the country, get a jump on the season by starting sweet peas indoors in six-packs or Jiffy pots. Harden seedlings off for at least a week, and then set them out into the garden as soon as the soil can be worked. If you garden in mild winter climates (Zones 8, 9, or 10), plant sweet peas in the late fall so they can develop and bloom in late winter and early spring.
Sweet peas are happiest with their heads in the sun and their roots deep in cool, moist soil. When possible, plant low-growing annuals in front of them to shade their roots.
Choose a well-drained site. Alkaline soil is best; sprinkle some powdered lime on the surface if your soil tends to be acidic.
Prepare a rich soil by mixing in generous amounts of compost and well-rotted manure to a depth of 2 feet. (Learn more about soil amendments and preparing soil for planting.)
Prior to planting, you’re going to want to dig a nice deep trench of about 4 inches in depth.
After you dig the trench, make holes with a pencil, drop in the seeds, and press down on the soil to firm it and shut out any light.
Before planting, soak the seeds in water for 24 hours. Then nick the seeds with a nail file before planting to speed sprouting. You do not need to soak seeds in a temperate climate.
