Best Tradescantia ‘Sweet Kate’ Spiderwort Plants and Seed Alternatives
For the named cultivar Tradescantia ‘Sweet Kate,’ the Perennial Farm Marketplace #1 container plant is the closest match in this selection; its listing specifies brilliant gentian-blue flowers. The other choices are different spiderwort cultivars or species, or seeds rather than established ‘Sweet Kate’ plants. Choose a live plant for a more direct start, or consider seeds if you want to grow spiderwort from seed and accept that the listings do not identify them as ‘Sweet Kate.’

| Outsidepride spiderwort seeds | Buyers seeking a larger listed seed quantity | 1,000 seeds; blue-violet blooms |
Perennial Farm Marketplace ‘Sweet Kate’

This is the most direct choice for someone searching specifically for Tradescantia ‘Sweet Kate.’ The listing names Tradescantia andersoniana ‘Sweet Kate,’ describes it as a perennial, and identifies the flower color as brilliant gentian blue. It is offered in a #1 container, making it a live-plant option rather than a seed packet.
- Best for: Buyers who want the named ‘Sweet Kate’ cultivar and blue flowers.
- Why it was selected: It is the only listing in this group that explicitly names ‘Sweet Kate.’
- Limitation: The product information provided does not specify mature dimensions, growing conditions, or the plant’s shipping condition.
Perennial Farm Marketplace ‘Concord Grape’

‘Concord Grape’ is a related spiderwort alternative, not the ‘Sweet Kate’ cultivar. The listing identifies Tradescantia x ‘Concord Grape’ as a perennial in a #1 container and describes its flowers as violet purple. It may suit buyers who want a live spiderwort with a different listed flower color.
- Best for: Gardeners who prefer violet-purple flowers over the gentian-blue color listed for ‘Sweet Kate.’
- Why it was selected: It offers a clearly named Tradescantia cultivar in a live-plant container.
- Limitation: Choose another listing if having ‘Sweet Kate’ specifically is essential; this is a different cultivar.
Three Ohio Spiderwort Live Plants

This listing offers three live plants identified as Tradescantia ohiensis, rather than the named ‘Sweet Kate’ cultivar. Its description highlights a hardy native perennial with violet-blue flowers and a bloom period from late spring through summer. It also lists full sun to part shade and drought tolerance.
- Best for: Buyers looking for multiple live plants or an Ohio spiderwort species option.
- Why it was selected: The listing gives a plant count and several useful growing and bloom details.
- Limitation: It is Tradescantia ohiensis, not ‘Sweet Kate’; the listed growing preferences may not match every garden site.
Tradescantia Ohiensis Perennial Seeds

This seed listing is labeled as perennial Tradescantia spiderwort and Widows Tears/Tradescantia ohiensis. The title states that it contains more than 1,100 seeds for planting. It is a different purchase type from the container-grown ‘Sweet Kate’ listing: buyers start with seeds rather than a live plant.
- Best for: Gardeners who want to start Tradescantia ohiensis from seed.
- Why it was selected: It provides a seed-based option with the species named in the listing.
- Limitation: The product title does not identify these as ‘Sweet Kate’ seeds, and seed starting requires growing the plants from seed.
Outsidepride Spiderwort Seeds

Outsidepride’s listing describes 1,000 perennial spiderwort seeds with dark-green foliage and blue-violet clustered blooms. It also characterizes the seeds as drought-tolerant and low-maintenance and mentions pollinator gardens. The supplied product title does not name the ‘Sweet Kate’ cultivar, so this is better treated as a general spiderwort seed option.
- Best for: Buyers who want a listed quantity of 1,000 seeds and are open to spiderwort beyond ‘Sweet Kate.’
- Why it was selected: It offers a clearly stated seed count and flower-color description.
- Limitation: The listing does not identify the seeds as ‘Sweet Kate’; confirm the plant identity if a particular cultivar is required.
Buying Guide: How to Choose Spiderwort
Do you need the ‘Sweet Kate’ cultivar?
Check the botanical name and cultivar in the listing. Of these five options, only the Perennial Farm Marketplace plant explicitly names Tradescantia andersoniana ‘Sweet Kate.’ The ‘Concord Grape’ plant and Ohio spiderwort listings are alternatives, not interchangeable names for ‘Sweet Kate.’
Should you buy a live plant or seeds?
Choose a container plant or live plants if you want to begin with an established plant. Seeds can be an option for gardeners who want to start plants themselves, but the seed listings do not claim to be ‘Sweet Kate.’ Compare the exact product identity before ordering.
Which flower color and growing details matter?
The ‘Sweet Kate’ listing specifies brilliant gentian blue, while ‘Concord Grape’ is described as violet purple. The Ohio spiderwort live-plant listing gives violet-blue flowers and specifies full sun to part shade, with drought tolerance. The other listings provide fewer growing details in the supplied descriptions, so avoid assuming identical site preferences.
What should you verify before buying?
Confirm the plant name, whether the item is a seed or live plant, and the quantity or container description. For a cultivar-specific garden, prioritize listings that name the cultivar directly. For broader spiderwort planting, compare flower color and the growing information actually stated in the product description.
