Preparation

What you'll need:

Clements' Groundsel seeds or young plants (check local nurseries or online for availability)

A pot or garden space with well-draining soil

Basic gardening tools like a trowel and watering can

Some compost or organic matter to enrich the soil

When to start:

Clements' Groundsel is a pretty adaptable plant, but it does best when planted in early spring or fall. It enjoys cooler temperatures, so avoid planting during the hottest part of summer.

Finding a good spot:

This plant prefers partial shade to full sun. If you're planting it in your garden, look for a spot that gets morning sunlight but has some shade in the afternoon. If you're using pots, place them on a balcony or patio where they can get filtered light throughout the day.

Soil preparation:

Clements' Groundsel likes well-draining soil. If your soil feels too heavy or clay-like, mix in some sand or perlite to loosen it up. Adding a bit of compost will also give the plant a nutrient boost.

Planting

If you have seeds:

  1. Start by filling small pots or seed trays with moist soil.
  2. Sprinkle the seeds lightly on top of the soil—don't bury them too deep, just press them gently into the surface.
  3. Water lightly to keep the soil moist but not soggy.
  4. Place the pots in a cool, bright spot, like a windowsill with indirect light.
  5. Seeds should germinate in about 1-2 weeks.
  6. Once the seedlings have grown a few leaves and are sturdy enough to handle, you can transplant them into larger pots or your garden.

If you have young plants:

  1. Dig a hole in your prepared soil or pot that's slightly larger than the root ball of the plant.
  2. Gently remove the plant from its container and place it in the hole.
  3. Backfill the hole with soil, pressing down lightly to secure the plant.
  4. Water thoroughly after planting.

Planting tips:

  • Space each plant about 12 inches apart if you're planting in the ground to give them room to grow.
  • If using pots, make sure they have drainage holes to prevent waterlogging.
  • After planting, add a thin layer of mulch around the base to help retain moisture.

Growing Care

Watering:

  • Clements' Groundsel doesn’t like to be too wet or too dry. Water when the top inch of soil feels dry to the touch.
  • In hot weather, you may need to water every 2-3 days, but in cooler weather, once a week might be enough.
  • Always water at the base of the plant to avoid getting the leaves too wet, which can lead to fungal issues.

Feeding time:

  • Feed your Clements' Groundsel with a balanced, all-purpose fertilizer once a month during the growing season (spring and summer).
  • Don’t over-fertilize; a little goes a long way with this plant.

Sunlight and temperature:

  • This plant is happy in partial shade to full sun, but it prefers cooler temperatures. If you live in a hot climate, provide some afternoon shade.
  • It can tolerate light frost, but if a hard freeze is coming, cover the plant with a cloth or bring potted plants indoors.

Minor problem solving:

  • Yellowing leaves? You might be overwatering. Let the soil dry out a bit before watering again.
  • Wilting? Check if the soil is too dry, and water immediately if needed.
  • Pests? Clements' Groundsel is usually pest-resistant, but if you see aphids, spray them off with a strong jet of water or use an insecticidal soap.

Harvesting

When to pick:

Clements' Groundsel is primarily grown for its attractive foliage and yellow flowers rather than for harvesting. However, if you'd like to collect seeds for future planting:

  • Wait until the flowers have turned into fluffy seed heads (similar to dandelions).
  • Gently shake the seed heads over a container or paper bag to collect the seeds.
  • Store the seeds in a cool, dry place until you're ready to plant them again.

How to pick:

If you're pruning to encourage bushier growth or tidying up the plant:

  • Use clean scissors or pruning shears to cut back any leggy or dead stems.
  • Prune in early spring or after flowering to keep the plant looking neat and healthy.

After harvesting:

  • If you've collected seeds, label them and store them in a cool, dry place.
  • Keep an eye on your plant after pruning—it will likely produce new growth fairly quickly!
