Sweet Peas | Queen of the cut flower

Sweet peas are really easy to grow and one of the ideal ‘starter’ seeds for a beginner gardener.
One of the most rewarding plants to grow, sweet peas are truly the gift that keeps on giving for a gardener that enjoys cut flowers in their home. There are few things as satisfying as being able to fill a vase in your house with a fresh bunch of sweet peas in spring! Not only are they beautiful, but some varieties have the most incredible scent that will fill your entire house.
Autumn is the season to sow these beauties in South Africa and we decided to give you all the in’s and out’s so that you will be able to fill your own vase later in the year with a beautiful bunch of home-grown sweet pea flowers. We kick this series off by giving you a few reasons as to why you should be growing sweet peas in 2021:

It’s easy to grow them and they are quite hardy

They are quite hardy annuals (a plant that completes its life cycle from seed to seed in one growing season) that require very little attention if you do the following things right.

Choices! Climbers, bush or dwarf varieties…pink, purple, blue…

There are so many different types of sweet peas, one may feel a bit overwhelmed. An easy way to remember the difference is by distinguishing between ‘old fashioned’ and ‘modern’ varieties. The ‘old fashioned’ varieties tend to be highly scented whereas the more ‘modern’ varieties show off with large, showy or even frilly flowers. Colour is a matter of preference as there is also so many to choose from. Have a look at some of the sweet pea plant profiles below that we have in our knowledgebase:

You don't need a garden, a pot will do just fine!

Sweet peas do very well in containers as long as you provide support for climbing varieties and enough space for them in the pot. Remember that a container tends to dry out more quickly than a gardening bed, so more regular watering might be needed.

Heavenly scent

Sweet, just at the name implies! Some sweet pea varieties are so intensely perfumed that you might get the urge to bury your face in the blooms whilst inhaling the heavenly scent. Remember to look out for the scented / ‘old fashioned’ varieties when you buy your seed. Not all sweet pea varieties are scented.

Beautiful blooms

There is nothing more beautiful than a vase filled with sweet peas. There is something for everyone with a myriad of different colors, shapes, and forms. From frilly, dainty little flowers to others with flaked colouring - the choices are endless.

Bonus of seed saving for next year

Remember that they are annuals, and will thus only last for one growing season. If you would like to harvest your seed to plant next year, remember to not cut away all the flowers but to leave some to produce seed.

Perhaps these guys will inspire you to sow your first #SweetPea seeds this year! Remember to use the hashtag #sweetpea so that we can follow your journey.


Sweet pea time!!

Hi there, where can I find sweet pea plants / seedlings for my garden?


Sweet peas from seed. Speed at the end of April,. Now in bloom


The Tom Thumb Pea has become a new favorite of mine. It is incredibly sweet and tasty.


To encourage germination, soak sweet pea seeds overnight before planting them out. You'll have lots of sweet peas to enjoy in spring if you sow now! #timetosow #sweetpeas #edibleflowers #gardening #growyourown #gardeningisfun #growforit #growfromseed #sow

Start preparing your soil in strips or ridges for the sowing of Sweet Peas. Don’t forget the trellis or other support framework for them to climb up. #sweetpeas #whattosow #lifeisagarden
