Maintenance & pruning: None required; you may shear back old blooms if you wish but this is not necessary for continuous bloom.
Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:
Not sure just how many plants will fit in your garden? Our calculator gives you the exact amount of plants required for your space. Simply update the values and the calculator will re-calculate accordingly. Spacing information can be found in the 'How to Grow' tab on each plant's page.
This was the first time I have ordered plants online so I guess I was hoping for the plants to be in better condition. They spent 6 days in transit and when they arrived, both plants were in bad shape and one looks mostly dead. I planted them immediately hoping they recover. But at 1 week later it's clear that one is not going to recover, so I'm pretty disappointed. I can't say I have much trust in online live plant ordering after this.

They left Michigan on a Tuesday and arrived on Thursday. I opened them within minutes of their arrival. The creepers were great out of the box but these were dead. I planted them anyway hoping they would come back to life but no such luck.
EDIT (4/2025): Thank you to Great Garden Plants for the replacements of the ones that died. But none of them made it through the winter. The roots are very shallow. I suppose it is my fault for thinking I could plant them in August (and September for the replacements) and think they could make it. Perhaps with an April planting they would have had a chance. I am going to run sod right up to the driveway and give up on these.

This was my third order other orders had a problem with a couple of plants. They were fast with taking care of the problem. 5 stars for the plants I do have until now! These were disgusting! They credit me right away, but I really wanted to finish this part of the flower garden. I have 3 more areas next spring. DISAPPOINTED!

Beautiful plants… one was in rough shape but it was replaced without issue and they are doing beautifully
Not happy! Half the plants arrived dead
Hello! It is common for plants to experience slight stress from shipping, as they have not experienced their ideal growing conditions at this time. We recommend placing plants in a cool, shaded spot out of direct sunlight for 24-48 hours after unpacking them. This allows them a recovery and acclimation period before planting. If you must hold them longer, place them out of direct sunlight, wind, heat, and cold, and plant as soon as possible. Please email your order number and pictures of your plants to us to start the claims process, and we can make sure your plants are on the right track!
Ordered almost a dozen of these to brighten up three tired flower beds that get full sun. I am beyond impressed with their color and immediate impact. Every plant has beautiful, vibrant dark yellow blossoms with more buds on the way. The dark green foliage contrasts with the flowers to really “pop.” They remind me of marigolds but with the perennial staying power. So thrilled about this plant- I highly recommend.
Love the color, I need a few popps of bright yellow.
It's blooming nicely & I love the color! But, I still say, get rid of that stupid metal clip that you use when you ship plants. It's NOT necessary!
First one didn't make it. The weather was unusual and it may have been too early to plant. GGP replaced it without question. It is doing very well (as are all the other plants I ordered). I plan on using GGP in the future.
I ordered six Tickseed plants. They were all damaged upon delivery. I think they will grow just fine, but was disappointed in the packaging considering how much I spent on the plants.

I've had real good luck with Great Garden Plants. Their plants are nicely sized, healthy, and adapt quickly to my garden.
I was late in planting but they appear well on their way.
Received in excellent shape. Opened up package and watered. Let sit for a day or two and planted in the garden. Looks good and hopefully you will bloom in Spring.
Plants died before I could even plant them properly.

Happy with purchase.
The plants were really healthy on arrival and have done well in a container on my balcony. There are constantly new flowers appearing. Really hope it lasts through summer.
Is it too late to plant perennials in zones 4/5
No, definitely not - you can safely plant through late September, even into early October.
